The Saramonic BMCC-A01 is a two-channel XLR audio adapter, specially designed for Blackmagic Camera. A wide-variety of professional audio devices like XLR mics, wireless mics, boom mics and mixing boards can be connected to the camera via this adapter. Audio from your microphones will be passed to your camera by BMCC-A01 with or without the use of a 9V battery. Advanced functions such as level meter, 12V/48V phantom power and LED indicator are available by using a battery. It allows you to record high quality audio directly to the camera, eliminating the need of a separate audio recording.
